What is the Steem blockchain and how is it related to Steemit?

Steem is a blockchain-based social media platform that allows users to create and share content, as well as to earn rewards for their participation. Steemit is one of the most popular applications built on the Steem blockchain.

The Steem blockchain was created in 2016 by Dan Larimer, Ned Scott, and a team of developers. It is designed to provide a decentralized and censorship-resistant platform for content creation and social interaction. The blockchain uses a delegated proof-of-stake (DPoS) consensus mechanism to secure transactions and maintain the integrity of the network.

Steemit, on the other hand, is a social media platform that is built on top of the Steem blockchain. It was launched in 2016 and has since become one of the most popular applications on the Steem network. Users on Steemit can create and share content, comment on other users' posts, and vote on content they like. Users can earn rewards for their participation in the form of STEEM tokens, which can be exchanged for other cryptocurrencies or fiat currencies.

Overall, the Steem blockchain and Steemit platform are closely related, with Steemit being one of the most widely-used applications built on the Steem blockchain.
